Yes: There is an anal sphincter which is a set of muscles that open and close the anus to allow for defecation. It relaxes and opens to permit passage of fecal contents and may remain relaxed after bowel movements for a period of time before regaining tone. This is normal. It is unlikely a result of your medications.
